Findings and how to fix them (6)

HSTS missing high

Add 'Strict-Transport-Security: max-age=31536000; includeSubDomains' so browsers never downgrade to http.

No Content-Security-Policy medium

A CSP limits which scripts can run and blunts XSS. Start with 'default-src 'self''.

Clickjacking protection missing medium

Set 'X-Frame-Options: DENY' or a CSP 'frame-ancestors' directive.

X-Content-Type-Options missing low

Set 'X-Content-Type-Options: nosniff' to stop MIME sniffing.

Referrer-Policy missing low

Set 'Referrer-Policy: strict-origin-when-cross-origin' to avoid leaking URLs.

Permissions-Policy missing low

Restrict camera, microphone, geolocation etc. with a Permissions-Policy header.
